- Symbol: A symbol is a visual representation that stands for or represents something else. It can be a graphic or an image that carries a specific meaning or represents an idea, concept, or entity. Symbols can be universal or cultural-specific, and they often convey complex ideas or emotions in a concise and abstract manner. - Sign: A sign is a physical or observable object or action that indicates the presence or existence of something. It can be used to give direction, provide information, or communicate a message. Signs are usually direct and straightforward in their meaning and are often used in public spaces or on roads to communicate with people. - Signal: A signal is a specific action, sound, or gesture that is used to communicate a particular message or command. Signals are often used in situations where verbal communication is not possible or where it is necessary to communicate quickly and efficiently. Signals are commonly used in transportation systems, sports, and military operations. - Mark: A mark refers to a visible trace or indication left by something or someone. It can be a physical imprint, a stain, or a spot that is used to identify, distinguish, or indicate a particular characteristic or presence.
